Wammy

Privacy Policy ​

Last Updated: November 2026

Wammy ("we", "us", or "our") is a free, open-source Android reader application for manga, manhwa, manhua, and light novels. We believe privacy is a fundamental right. This Privacy Policy describes how Wammy handles information when you use our application.

1. Zero Tracking & No Data Selling ​

  • We do not track you: Wammy does not sell, rent, or monetize your personal information or reading history.
  • Local-first design: Your library, categories, reading progress, and downloaded chapters reside entirely on your local device.

2. Discord Integration ​

When you connect your Discord account in Wammy:

  • Authentication: We use Discord OAuth2 with Proof Key for Code Exchange (PKCE).
  • Scopes Requested: Wammy requests only the identify scope.
  • Data Accessed: We only read your public Discord user ID, username, and avatar to identify your connected profile and display your account in Settings.
  • Rich Presence: If enabled, Wammy displays your current reading activity (e.g. title and chapter) as your Discord status.
  • What We Do Not Access: We cannot read your private messages, access your friends list, join servers on your behalf, or send messages as you.

3. Cloud Backups & Sync ​

  • If you enable DropSauce, Google Drive, or self-hosted cloud sync, your library metadata and reading history are encrypted and transmitted directly between your device and your chosen cloud storage provider.
  • We do not run intermediary servers that store or inspect your backups.

4. Diagnostics & Crash Reporting ​

  • Optional Telemetry: Wammy includes optional, privacy-respecting crash reporting (Firebase Crashlytics) to help developers diagnose crashes and bugs.
  • Full User Control: You can toggle Crashlytics and anonymous analytics on or off at any time under Settings > Security and privacy.
  • Reports contain non-identifiable technical data such as device model, OS version, and stack traces.

5. Third-Party Sources ​

Wammy enables users to browse content from third-party online sources and repositories. When you browse or download chapters from external sources:

  • Your requests go directly to those external websites.
  • Those services have their own independent privacy policies and terms.

6. Open Source Verification ​

Wammy is fully open-source under the Apache License 2.0. The complete source code is publicly auditable at: https://github.com/Wammy-app/Wammy
